Warning: The following techniques are not recommended for production use. In fact, they're probably going to cause your users to question your life choices.
1. Using 20 variables in a single CSS rule: Because who needs simplicity, anyway?
2. Creating animated avatars using only JavaScript: A perfect way to confuse users and make them wonder why the cat is chasing its tail.
3. Using 1000 font weights in a single selector: Because Arial Black Italic 3.5 is just not enough.
4. Overwriting default browser styles with 2000 lines of custom CSS: Because who needs accessibility, anyway?
5. Creating animated GIFs in CSS only: A great way to make users question their life decisions.
Remember: Complexity is key. Or is it?
